More on widescreen monitor

| Apparently a Matrox G550 doesn't do 1680x1050. It is an older card so I
am not surprised. I googled up some links that seem to suggest that it
will go higher than 1280x1024 but the Matrox web site says absolutely not.
I have experimented with new modelines but can't make any work in
widescreen.
So...
I cranked up a Knoppix live cd and got the usual list of resolutions
starting with 1280x1024 at the highest. However, in the
/etc/X11/XFConfig-4 file there are a list of "Extended modelines with GTF
timings" that go way beyond that resolution. In fact it goes clear up to
"Modeline "1920x1200" 193.16 1920 2048 2256 2592 1200 1201 1204 1242
-HSync +HSync".
Cycling through the modes with Ctrl-Alt + only gets the standard settings.
Googling about Extended modelines only brings up other's config files with
the same entries as mine. So far all the man pages I have looked at don't
mention them.
Anyone know what an extended modeline is? And how to access it?
I am going to need a new adapter card, which is no big deal. Just not
sure which one to get, other than it probably needs to be nVidia based.

You don't care about modelines.
If the card can't do more than 1280x1024, try setting that in the
Screen section, and then look at /var/log/Xorg.0.log to see what
it is doing or not doing.
Without looking at the log, all of this is merely flailing away for
no purpose.

You don't care about modelines!

With an LCD, it is a total waste of your time!

I don't know that it has to be nVidia based, but do make sure it
can handle the 1920x1200. I'd guess that almost anything you
can buy new today will...

Supported resolution/depth modes are based on how much memory your video
card has. Check that, and do some simple (and obvious) calculations.
For example: to get 1024x768x32bpp, you need:
251658 bits, /8 = 3145728 bytes, but since we're in 2^x, that's 4mb.
You need 4mb of video memory to display 1024x768x32.

***Lots of googling later.
Interesting that any version of Xfree above 4.xx doesn't need modelines
but it still creates dozens of them. I counted 54 on a machine with a
21" monitor (crt).
Anyway, a new low end Nvidia card eGeforce 6600le and the downloaded
binary from Nvidia did the trick.
And what blew me away is that the script from Nvidia just ran, installed
the driver, updated XF86Config and said ready to go - and it worked the
first time. No missing libraries, or failure to find symlinks, or other
missing dependency stuff that we have all come to love in Linux software
from folks who don't really want to fool with it. We'll all be Windows
weenies if this keeps up.
Go Nvidia!
Thanks

You may even have to craft one. For example if you decide to run twin
1920x1200 panels,it is likely that you'll have to at least lower the dot
clock. But... I dunno.. maybe you can do that without a modeline? I've
never been successful without a crafted modeline.
I've always had to create my own modeline for 1920x1200 it seems...
You can always find some at http://nvnews.net (look at the
Nvida Linux forums there).

Glad it worked. Not sure about your last sentence though.

Would be nice to see them go Open Source at some point. My guess is
that ATI (oddly enough) will be first.

Sorry. Just a little light sarcasm on my part. What I meant was that if
Linux keeps getting easier then eventually we won't need any
higher technical skills than the folks using that other OS
